Abstract
This article combines the properties of both types of ferroelectric materials (inorganic ceramic and liquid crystal), to obtain a plastic composite exhibiting high polarization. To realize this target, a liquid crystalline nanocomposite was prepared comprising a polymer (PM6R10) and a monomer (M6R6) mixture in a 2 : 1 ratio, PM10M6 and BaTiO3 nanoparticles (NpBT). To prepare the nanomaterials, we used the calcinations method of a gel precursor. By studying the dependence of the morphological and structural characteristics with the annealing time at 1000°C, we obtained a product that possess the properties suitable for the purpose of this study. Then to PM10R6, NpBT were added at a concentration of 5%, with and without oleic acid (OA). Measurement of the pyroelectric signal reveals that the addition of NpBT significantly increases the pyroelectric response of the material compared to the original composite. However, when adding OA as the compatibilizer, the pyroelectric signal and therefore their polar property practically disappears.
